Installation & Wiring Instructions
Mounting the Enclosure
Recommended installation location is above plants and benches to avoid water damage to the hub connectors and circuit board. Locate the canopyLINK centrally to where sensors will be installed. Consider rolling bench locations and sensor cable extensions (available from Growlink) if necessary.
Follow these tips for best results:
- Do not install below misters, foggers, humidifiers and other water equipment.
- Avoid locations with condensation.
- Prevent condensation from entering the housing; locate the hub above cable runs. for connections.
Connections
M8 Connection
M8 connections are threaded male end connections with four pins. To connect M8 type sensors to the canopyLINK, an adapter cable may be required if the sensor doesn’t have an appropriate 4-pin female M8 connection. Growlink has many adapter types available for purchase. 
HUB Connection Port: RJ-45 connector port for power & data.
M8 Port (x8): M8 connector port for compatible sensors.
Power LED: Green LED indicates the canopyLINK has power from the HUB connection.
24VDC Port: Port for 24VDC from included 24VDC power adapter.
Mobile App Setup Guide
1) Plug in your Growlink device to power it on. The LED should be blinking blue. If not, hold the SETUP button until status light flashes blue rapidly (12-15 seconds).
2) Download the Growlink app from the Apple App Store, or Google Play Store.
3) Go to portal2.growlink.com/signup or tap the ‘Sign Up’ button at the login page of the Growlink Mobile App to create a Growlink Account: 
After creating your account, a verification email will be sent from ‘no-reply@growlink.com’ to the email address set for your newly created account. One must verify your email address in order to utilize your newly created account.
4) Open the Growlink Mobile App and login to your newly created and verified account: 
5) Tap the icon of three lines in the top-left of the Mobile App, then tap the Hardware button in the following menu:
6) One can add a controller to an existing room, or tap the ‘+Add’ button in the following page to add a new room to your account. This is the container that will hold the future controller registration:
7) If you are creating a new Room, provide a name for the Room, the Square Footage of the Room, and the Room Type, followed by tapping the 'Create’ Button to finish creating that room:
8) Once an existing room has been selected or a new room has been created, tap the ‘Continue’ button to begin registering the controller to your account:
9) Tap the LINKS button in the following page.
10) Select the ‘Add Devices’ option to add the controller to the specified room:
11) Select the ‘canopyLINK’ option in the following menu that populates:
12) If you’re registering your CanopyLINK as a standalone device, tap the ‘Add as a standalone Wi-Fi Device’ option. LINKS connected via WiFi can only connect to secured 2.4GHz networks and cannot connect to WiFi networks that are not secured with a password and/or 5GHz WiFi networks.
If you’re registering your CanopyLINK to a LINKS Hub, tap the ‘Add to a HUB’ option:
Further instructions on how to add equipment to an existing LINKS Hub can be found HERE.
13) If registering the canopyLINK as a standalone controller, the app will then search for a nearby device in listening mode. Ensure your canopyLINK is in listening mode by holding down the setup button for at least 3 seconds.
14) Once the canopyLINK is paired to your phone, designate the network you wish to connect the canopyLINK to and input the credential for that network:
15) Once WiFi credentials have been provided, all that is left is to name the controller and tap the ‘Next’ button on the following screen. The Mobile app will then attempt to register the controller to your account and pass those credentials towards the controller.
16) Once the canopyLINK has been registered, the app will populate the current sensors being detected by the canopyLINK, where you can then name the sensor inputs and register them to your canopyLINK:
To skip a specific module from being registered to your canopyLINK, tap the ‘Skip’ button at the bottom of the wizard. Once the sensors have been named to your liking and any required fields for the module have been designated, one can tap the ‘Next Device’ button to move onto the next module detected by the canopyLINK.
17) Once successfully connected, the following success message will display. Tap the ‘Add Equipment to this Controller’ to add more hardware to this controller, Tap the ‘Edit Controller Profile’ button to update the Controller Profile Settings, or tap the ‘Go to Room Dashboard’ button to view the dashboard for the newly connected controller:
Adding Sensors to an existing canopyLINK
1) In order to add sensors to an existing canopyLINK, start by wiring the new sensor to your canopyLINK, then use the Mobile App to add that registration to your room. This can be done by tapping the icon of three lines in the top left of the Mobile app, followed by tapping the Hardware button within the Growlink Mobile App:
2) Next, Select the room you are wanting to add the sensor too, followed by tapping the ‘Continue’ button:
3) In the Add Hardware wizard, tap the ‘LINKS’ option:
4) In the following page, tap the ‘Add Sensors’ button:
5) Select the type of sensor being added to the canopyLINK, followed by specifying what specific canopyLINK the sensor is being added to (if there are multiple canopyLINKS):
6) Once the canopyLINK has been selected, the app will populate the current sensors being detected by the canopyLINK, where you can then name the sensor inputs and register them to your canopyLINK:
7) Once all currently detected modules are registered or skipped, a final confirmation window will populate:
If you wish to add an additional sensors to the canopyLINK, connect the sensor to the canopyLINK while at this screen, then tap the ‘Check for new equipment’ button. Once all sensors have been registered to the canopyLINK, tap the ‘I’ve registered all connected equipment’ button to exit the Add Hardware wizard.
Troubleshooting
Controller not showing up on my list of devices to connect:
Check your phone or tablet and ensure Bluetooth is enabled.
Hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Then refresh the device list on your phone or tablet.
Unplug the unit for 10 seconds and then plug the device back in and wait for the LED lights to stop changing colors (typically 15 seconds). Then refresh the device list on your phone or tablet.
Controller didn’t connect to Wi-Fi:
If unsuccessful in the first attempt to connect the controller to the Wi-Fi network, hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Once rapid flashing becomes visible, immediately release the Setup button. This will put the controller into Listening Mode (Blinking Blue). Now, restart the connection process outlined in the Quick Setup Guide section above.
The Wi-Fi network being used has changed:
In the event the controller needs to re-connect to an existing or new Wi-Fi network, put the controller back into Listening Mode (see above) and follow the Controller Connection process outlined in the Quick Setup Guide section above.
